Abstract (en)
An improved method for culturing a yeast transformed by a recombinant plasmid which is prepared by inserting a hepatitis B virus gene into a plasmid carrying a depressible acid phosphatase promoter of a yeast under controlling of the promoter and thereby producing HBs antigen, which comprises culturing the transformed yeast in a semi-synthetic medium containing yeast extract, an inorganic ammonium salt, an inorganic magnesium salt and either or both of glucose and saccharose.
